Grease lubrication for railway axlebox bearings .

The SKF R3 railway bearing test rig, operating in accordance with EN 12082, has evolved through SKF’s considerable experience in evaluating railway bearing performance. The rig consists of a shaft with two support bearings, which are mounted inboard. The axlebox bearings are mounted on both ends of the shaft. Actuators provide radial and ...

The test results show the clear benefits of the polymer cage material (fig. 4). At lower speeds, in particular, roller slip is dramatically decreased. The stabilised temperature after the running-in phase of axlebox bearings equipped with a polymer cage is around 15 °C lower than for a brass cage.

CDA - RAIL TEST RIG FOR AXLEBOX BEARIN

Axlebox housings and bearings are air-cooled, which has a considerable influence on grease operating life. The test rig is therefore equipped with an air stream simulation facility, which generates wind speeds up to 10m/s. On another test rig at Schweinfurt, axlebox bearings and their original housings undergo leaktightness water spray tests.

Wong [60] studied static and dynamic axial crushing behaviour of closed hat sections. To aid his research Wong was largely responsible for the design and build of an impact test rig which could hurl a 60 kg mass at a specimen with a velocity of up to 60 miles per hour. Wong carried out about 500 static and dynamic crushing tests.

The structure of a novel axle bearing endurance test equipment which we developed and the progress of an endurance test of axle bearings which are used on bogies of the series E5 are reported as the subject of this paper. The test equipment enables a test under a same high speed condition of over 320 km/h simultaneously for four bearings.

SKF Grease Test Ri

SKF Grease Test Rig RST is used for shear stability tests on lubricat-ing greases. The device simulates the effect of squeezing grease between the rollers and the outer ring raceway of roller bearings. Each test cylinder contains a heavy roller and is filled with a certain quantity of the sample grease. The RST allows up to four test cylinders ...
